Positive role of pain:

Draws attention of the patient who will alert the healthcare provider

Provides a warning of tissue damage

Induces immobilisation to allow appropriate healing

Allows to monitor response of the treatment

Negative effects of painNegative effects of painEmotional & physical suffering

Increased oxygen consumptionImpaired bowel movement

Delays mobilisation – risk of Thrombo-embolism

Sleep disturbance

Cardiovascular side effects

Assessment of painAssessment of painAssess pain at rest & on movement to evaluate functional status

Monitor response to Rx Before & After admn of Analgesic  pain is intense -evaluate, treat, and re-evaluate every 15 min initially in Post Anaesthesia Care Unit

(PACU), then every 1-2 h
